Yeah, zero emissions on the road, but not in reality. The energy to run this golf-cart comes from somewhere, typically coal power plants. While it has lower emissions per unit power due to high volume, it's hardly ZERO. Also, charging the car via your home power outlet will move you to the highest slab as far as power consumption goes, so it won't be as cheap either. Given that except in the big metros, power supply is iffy, I wonder if people will try charging their cars with portable generators :D.
Electric cars can actually be much faster than the ones ganguly is trying to sell. There have been commercial electric cars in the US that were highway worthy (i.e. could do 70-80mph, or ~130kmph). I guess the last thing we need is to allow these cars on highways. With their low speed, they will clog up traffic, much like rickshaws. Replacing rickshaws with Nanos might actually help average road speed, as long as the rickshaw-wallas don't slow down when they are looking for customers or stop bang in the middle of the road to pick customers up. This thing is ok for internal city roads where you cannot cross 50k anyway.
